5.5.8 Default Imports

Since Griffon 0.9.1 default imports per artifacts are supported. All Groovy based artifacts will resolve classes from the `griffon.core` and `griffon.util` packages automatically, there is no longer a need to define imports on those classes unless you require an static import or define an alias. An example of this feature would be as follows.

    class MyController {
        void mvcGroupInit(Map args) {
            println Metadata.current.'app.name'
        }
    }

The `Metadata` class is defined in package `griffon.util`. There are additional imports per artifact type, here's the list of default definitions

- Model

- groovy.beans -> @Bindable, @Vetoable
- java.beans -> useful for all PropertyChange* classes

- View (when using Swing)

- java.awt
- java.awt.event
- javax.swing
- javax.swing.event
- javax.swing.table
- javax.swing.text
- javax.swing.tree

The list of imports per artifacts can be tweaked or changed completely at will. You only need to specify a file named `META-INF/griffon-default-imports.properties` with the following format

    <artifact_type> = <comma_separated_package_list>

These are the contents of the default file

    views = javax.swing., javax.swing.event., javax.swing.table., javax.swing.text., javax.swing.tree., java.awt., java.awt.event.
    models = groovy.beans., java.beans.

Imports are cumulative, this means you a package can't be removed from the default list provided by Griffon.
